| 摘 要： | 将一种改进的DEA模型-超效率DEA(SE-DEA)模型1]拓展到区间投入产出情形,得到区间SE-DEA模型.基于此给出了求解每个DMU的区间超效率值的上限和下限的确定型DEA模型.该区间超效率值较传统的区间DEA模型更具区别性,能对所有DMU进行充分排序.在此基础上,将所有DMU分为三类.最后给出区间SE-DEA模型在建筑业效率评估中的应用算例分析.

| Abstract: | When the input and output data of a modified DEA-Super Efficiency DEA are interval numbers,the SE-DEA model was extended to interval SE-DEA.Based on this principle,models of getting upper and lower bounds of the super efficiency scores for each DMU are set up.This interval super efficiency is more discriminative than that of a traditional interval DEA.As a result,all the DMUs can be sorted fully and classified into three types.Finally,an example of evaluating and forecasting efficiency on the construction industries is given. |
